Mary Sue and others,
In taxonomy, rank (e.g.. genus, subgenus, species, subspecies and variety)
is arbitrary.  A group recognized at the subgeneric rank could be equivalent
to either genus
(in which the previous generic rank would be elevated to section or tribe)
or specific rank with a full breakdown of subspecies and varieties.  The
elevating and reducing of rank is mostly done to compartmentalize each group
that has a separate evolutionary lineage and changes in names/groups is
fully intended to accurately reflect the evolution of a group.
The genus Moraea are still  irids!  The day that changes, I could see a
complaint coming.  Manning and Goldblatt have such insight into these groups
we must accept their treatemnt until a better alternative comes along.
I believe that the Amaryllidaceae is being sunk back into the Alliaceae,
along w/ the Agapanthaceae, making them the Allioideae, Amarylloideae and
the Agapanthoideae subfamilies, crunching other ranks down into tribes,
sections, etc...I have not actually read these re-revisions but have heard
that they are coming.
